The chip has enough ram (32k) that the 256 byte buffer might be tolerable, especially if there's a way to multi-purpose it with the terminal line buffer or other areas that Forth needs to keep available some of the time. Plus there is 256k of flash, so maybe it's possible to use a 256 byte block as temp storage so you can rewrite a 64 byte page by copying the surrounding pages to the temp block and back, i.e. you need only 64 bytes of ram buffer instead of 256. FWIW, there's now an alternate version of the board with a "hard disk" (microSD slot): https://www.adafruit.com/products/2796 giving essentially infinite storage for something like this. I'm liking these boards more and more. They apparently include a 32 khz crystal so you can have an RTC if you don't reset or unpower the board. And there's a cute OLED display that plugs on top: https://www.adafruit.com/products/2900 This is tempting for many things.
